Does Keysight still offer analog outputs for the 8163x optical power sensor modules?

Keysight Technologies offers several different optical power sensors:

The (older and now obsolete) 8153x optical power sensors have an analog output and operate in the 8153, 8163 and 8164 mainframes.

The (older) 8163xA optical power sensors operate in the 8163, 8164 and 8166 mainframes. These power sensor modules do not have an analog output. The 81635A dual channel power sensor is still available.

The (newer) 8163xB optical power sensors operate in the 8163, 8164 and 8166 mainframes. These optical power sensor modules do have an analog output.
